ARNOLD, OF SAME PLACE.

SHOE-SOLE-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 304,689, datedSeptember 9, 1884. Application filed May 26, 1884. (No model.) i

To all whom it may concern,

Be it known that I, EDWARD FRANcIs AR- NOLD, of North Abington, in thecounty of Plymouth, of the State of Massachusetts, have invented a newand useful Improvement in Shoe-Sole-Sewing Machines; and I do herebydeclare the same to be described in the following specification andrepresented in the accompanying drawings, of which- Figure'l is alongitudinal and vertical section of part of a sewing-machine embracingmy invention, the nature of which is defined in the claims hereinafterpresented. Fig. 2 is a transverse and median section of the horn forsupporting the looper and the shaft of its operative pinion on line as00, Fig. 1. Figs. 3 and 4 are hereinafter explained.

Prior to my invention the horn, when provided with a straight shaftextending longitudinally within it throughout nearly its entire length,as shown in Fig. 1, has been arched convexly on its upper edge,lengthwise of it, from its heel to its toe.

In carrying out my invention I make the horn shown at A in Fig. -1, witha recess or notch or reversed arch in its upper part, as shown at a b 0,such recess being to allow the heel portion of theshoe (shown in dottedlines at B) to extend down within such recess while the top portion ofthe sole of such shoe may be in the act of being sewed to the upper andinsole.

The convex curved line d a 0 cf represents the ordinary curve of theupper edge of the horn, from which it will be seen that without thenotch, recess, or depression a b c in the horn the heel portion of theshoe cannot be de pressed below the line a 6 without binding or breakingdown or crimping the leather of the upper at the heel, which is veryobjectionable for several reasons, and in ordinary solesewing machinestakes place generally while the sole is being sewed, near its toe, asthe shoe has to be depressed at the heel, in order to get the hornsufficiently up into the toe part of the upper. I also have the horn atitsupper end or part toenter the toe of the upper of a shoe providedwith a cap curved or arched directly over and in front of the looper,(see Fig. 4,) instead of having the front of the cap at right angles, orthereabo'ut, to

the upper surface of the cap, as it is usually made. \Vith myimprovementlast mentioned the horn can be pressed so closely up into thetoe of the upper as to enable the whole toe portion of the sole to besewed by the machine to the upper, which cannot generally beaccomplished when the end portion of the cap of the horn is, as shown inFig. 3, at a right angle, or about so, to the upper edge of the saidcap.

In the drawings, 'L represents the looper;

L, the needle; R, thecast-off, and S the shaft of the bevel-pinion P ofthelooper, such shaft having integral with it at its upper end the saidpinion. The looper is a beveled gear having a hole through it, as usual,for the passage of the waxed thread T. The cap extending over and downin front of the looper is shown at C. The arm or horn Ais recessed orgrooved along its under side to receive the shaft S, which is provided,as usual, with a bevel-gear, G, to engage with another such gear, II,carried by a horizontal shaft, I, that engages with the driving-shaft Mby means of bevel-gears K and L. The feeder is shown at F and thepresser at Q, such feeder, presser, needle, cast-off, and looper, andtheir operative mechanisms being such as in ordinary use in thewell-known sole-sewing machine termed the McKay Sewing-Machine.

I claim in the said sole-sewing machine- 1. The horn provided with therevoluble straight shaft S for the looper -pinion, and with the notch orrecess a be, for receiving the heel portion of the upper of a shoe whilethe sole of such shoe at its toe is in the act of being sewed to theupper and the insole, such shaft and recess being arranged in such horn,substantially as set forth.

2. The horn having the looper and its revoluble straight shaft S, andthe shoe-heel-receiving notch or recess a I) 0, arranged within it, (thesaid horn,) as set forth, in combination with the cap C, applied to theupper part of the horn and arched over and in front of the said looper,all being substantially as repre sented.

EDWARD FRANCIS ARNOLD.
